ICD-10-CM J62.8
CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

J62.8 is a billable ICD-10-CM diagnosis code for pneumoconiosis due to other dust containing silica. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 196 through 198. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Lung disease due to external agents.

For Medicare Advantage risk adjustment, J62.8 maps to CMS-HCC Category 280 (Chronic Obstructive Pulmonary Disease, Interstitial Lung Disorders, and Other Chronic Lung Disorders) under the V28 model, adding a risk factor of about 0.319 for a community, non-dual, aged beneficiary in payment year 2027.

General instructions on how these codes are used.

From Chapter 10 (J00-J99) Diseases of the respiratory system applies to 366 codes
  • When a respiratory condition is described as occurring in more than one site and is not specifically indexed, it should be classified to the lower anatomic site (e.g. tracheobronchitis to bronchitis in J40).

Clinical InformationClinical

  • Silicosis

    a form of pneumoconiosis resulting from inhalation of dust containing crystalline form of silicon dioxide, usually in the form of quartz. amorphous silica is relatively nontoxic.

Patient EducationClinical

Interstitial Lung Diseases

Interstitial lung disease is the name for a large group of diseases that inflame or scar the lungs. The inflammation and scarring make it hard to get enough oxygen. The scarring is called pulmonary fibrosis.

Questions About J62.8Overview

What is the ICD-10 code for pneumoconiosis due to other dust containing silica?

The ICD-10-CM code for pneumoconiosis due to other dust containing silica is J62.8 (sometimes written as J628). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is J62.8 (Pneumoconiosis due to dust containing silica) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report pneumoconiosis due to other dust containing silica on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does J62.8 group to?

When pneumoconiosis due to other dust containing silica is the principal diagnosis on an inpatient stay, it groups to MS-DRG 198, 197, 196, with relative weights from 0.7256 to 1.8335 depending on complications. Higher weights mean higher Medicare reimbursement.

Can J62.8 be reported with A15?

Not as a rule. The Excludes1 note at J62, which applies to J62.8, lists "pneumoconiosis with tuberculosis, any type in A15 (J65)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).

What is the ICD-9 equivalent of J62.8?

Under the General Equivalence Mappings, pneumoconiosis due to other dust containing silica converts to ICD-9-CM 502 (silica pneumocon NEC). The mapping is approximate, so confirm the match fits the documentation.

What HCC is J62.8?

J62.8 (pneumoconiosis due to other dust containing silica) maps to CMS-HCC Category 280 (Chronic Obstructive Pulmonary Disease, Interstitial Lung Disorders, and Other Chronic Lung Disorders), commonly written as HCC 280, in the CMS-HCC V28 model used for Medicare Advantage risk adjustment in payment year 2027. It mapped to HCC 112 under the retired V24 model. It also maps in the PACE (CMS-HCC V22), ESRD (V21), and ESRD (V24) models. It does not map to any RxHCC in the Part D prescription drug model.

Does J62.8 risk-adjust for Medicare Advantage payment?

Yes. When documented and reported on a Medicare Advantage encounter, J62.8 adds a risk adjustment factor of about 0.319 to the beneficiary's RAF score for a community, non-dual, aged enrollee (published V28 weights range from 0.209 to 0.390 depending on the payment segment). A more severe related category (HCC 276, HCC 277, HCC 278, and HCC 279) supersedes it when both are reported. See the full factor table on the HCC 280 category page.
